They were so common when I was a kid, it wasn't out of the ordinary, I thought everyone had more than one. Every ranch had either a porch or a yard full of them. Where the heck did they all go. I guess when they started growing feet people started putting them inside. And of course ranches become estates and estates sell things. I remember Mom buying a bowl from the estate of the Jack ranch. My brother has it now, it's a beautiful bowl, cost her $35 and she couldn't turn it down. Speaking of the Jack Ranch, mom's side of the family homesteaded near Shandon, and they all knew Howard. I didn't know him but heard stories, and I'm familiar with the country. I was sent this picture via email a long time ago, it was taken in the Temblor Range behind, well east of Shandon, and shows what can happen when it finally rains at the right time of the year out there.
View attachment 717036 Not trying to hijack your post, but being that you spent time in the Carrizo Plains, you probably also trapped the Jack Ranch. When I was a kid that was the last intact Spanish land grant, you could barely see the home place out across the flat north of hiway 40 there at Cholame, where James Dean got himself killed. These bowls were so common on my step kids ranch, their family tradition tells that when the property was first settled back in the 1850's they used the Indian bowls to set corner posts in the fences.
